Twelve finishes, one controlled process
24 Karat Gold Plating
Pure gold electroplating for maximum conductivity, corrosion resistance, and a rich, unmistakable finish. The choice for electronics, medical, and luxury work.
18 Karat Gold Plating
Hard-wearing alloy gold that balances brilliance with durability. Ideal for jewelry, wearables, and parts that see daily handling.
Rose Gold Plating
The warm, pink-hued gold alloy finish for jewelry, wearables, and design pieces that want something beyond yellow gold.
Platinum Plating
The hardest, most chemically resistant white finish we offer. A bright, tarnish-proof, hypoallergenic surface for luxury pieces, medical components, and parts that live in harsh environments.
Rhodium Plating
The brightest, most reflective white finish in the industry. Mirror-bright, scratch-resistant, and tarnish-proof — the standard for finishing white gold and protecting silver.
Palladium Plating
A durable white-metal finish that rivals gold and rhodium for wear resistance at a lower material cost. The smart choice for electrical contacts, connectors, and hypoallergenic jewelry.
Silver Plating
The most conductive finish available, for electrical, thermal, and lubricity applications — plus a brilliant decorative surface.
Nickel Plating
The backbone of decorative and engineering plating. Bright, sulfamate, and electroless options for corrosion protection, wear surfaces, undercoating, and rebuilding worn parts.
Copper Plating
Superb leveling, conductivity, and adhesion. The foundation layer beneath most bright finishes, and a finish in its own right for electronics and electroforming.
Zinc Plating
Sacrificial corrosion protection for steel fasteners, brackets, and hardware. The workhorse finish, built for production volume.
Chrome Plating
Mirror-finish chrome electroplating for automotive trim, fixtures, and restoration work, backed by our sister polishing division.
Black Finishes
Deep, dramatic black rhodium and ruthenium finishes for luxury jewelry, watch components, and statement hardware.
